Hello: Yes, that is a magnetic chalkboard. The substrate is medium density fiberboard, and it's treated with magnetic primer (Rustolium) and chalk board paint (Benjamin Moore). The magnetic part is tricky, and the primer is no longer very environmentally friendly, so consider it carefully. If you have an option to install a sheet metal substrate with the chalkboard coating, that might be a better solution now.

Hi! That bench is about 7' long, and 24" deep to match the adjacent kitchen cabinets. It has a painted wood back that's slightly inclined for comfort, and loose upholstery cushions in washable fabric. The seat height was put a little higher than the chairs, so that the bench works well for small children.

Hello! The table is custom, and as others have noted, there are quite a few sources for metal table legs on line. The top here is a heavy duty matte lacquer, but Ceasarstone would be a good choice for durability.

Here are 2 links to some table legs that are very similar to the ones pictured above.

What Houzz contributors are saying:

4. Include something for the little ones. If your household includes children, you know it can be a challenge keeping small hands busy (and out of hot pans) in the kitchen. Add a chalkboard wall, convert a low cupboard to a secret play area, or keep a bin of Play-Doh and art supplies within reach.

Keep the kids in mind. Minimalism meets parenthood in this clever contemporary breakfast nook. Soft cushions, bright colors and a chalkboard create a kid-friendly zone. As most parents know, this will result in dust chalk on the upholstery, so if you go this route, plan your fabrics accordingly.More: How to Love Your Kitchen More, Right Now | More kitchen guides

These setups will also encourage your kids to spend time engaged with you in the kitchen. Even if you’re cooking dinner and they’re working on a project, you’re spending time together. Isn’t that the most important thing about a family home?
